+
+    OD 2007-03-30 #i73788#
+    An instance of this class can be used to observe a thread in order to
+    be notified, if the thread has finished its work. The notification is
+    directly forward to its owner - an instance of IThreadListenerOwner
+    Note:
+    - A thread can only have one or none listener.
+    - The notification is performed via the ThreadID
